The effects of processing conditions on fiber length degradation were investigated in order to produce composites with higher performance. Nylon-6 was compounded with glass fibers in a twin-screw extruder for various combinations of screw speed and feed rate. Collected samples were injection molded and Izod impact and tensile tests were performed in order to observe the effect of fiber length on the mechanical properties. Also, by using the extruded and injection molded samples, fiber length distribution curves were obtained for all the experimental runs. Results show that when the shear rate is increased through the alteration of the screw speed and/or the feed rate, the average fiber length decreases. Impact strength, tensile modulus and tensile strength increase, whereas elongation at break decreases with the average fiber length.

Effects of twin screw compounding conditions on the mechanical properties of Nylon-6 glass fiber composites Cansever, M; Yılmazer, Ülkü (2000-05-11) The effect of processing conditions on fiber length degradation was investigated in order to produce higher performance composites. For this aim. Nylon-6 was compounded with glass fibers in a twin screw extruder for various combinations of screw speed and feed rate. Collected samples were injection molded and izod impact and tensile strength tests were performed in order to observe the effects of fiber length on mechanical properties. Also, by using the extruded and injection molded samples. fiber length di...
Effects of injection molding conditions on the mechanical properties of polyamide/glass fiber composites Cansever, Cahit Can; Yılmazer, Ülkü; Department of Polymer Science and Technology (2007) In this study, effect of injection molding process parameters on fiber length and on mechanical properties of Polyamide-6 / glass fiber composite were investigated to produce higher performance composites. Polyamide-6 was first compounded with an E-grade glass fiber in a co-rotating intermeshing twin screw extruder. Then, by using this composite, twenty-five types of experiments were performed by injection molding by changing the barrel temperature, injection pressure, hold pressure, mold temperature, cooli...
Characteristics of HfO2 and SiO2 on p-type silicon wafers using terahertz spectroscopy Altan, Hakan; Pham, D.; Grebel, H.; Federici, J. F. (IOP Publishing, 2007-05-01) The effect of high-kappa dielectric HfO2 films on 200 mm diameter p-type silicon substrates was investigated and compared with conventional dielectric material, SiO2. We employed all-optical characterization methods using terahertz (THz) time-domain spectroscopy and visible cw pump/THz probe spectroscopy. Measurements were performed on two sets of samples, each set containing both HfO2 and SiO2 coated wafers with varying thickness of oxide layer. One set had a protective coating of either photoresist or Si3...
Effects of sensitivity derivatives on aerodynamic design optimization Eyi, Sinan (Informa UK Limited, 2007-10-01) The effects of sensitivity derivatives on the performance of aerodynamic design optimization were evaluated. Sensitivity derivatives were obtained by both analytical and finite-difference approaches. A sensitivity code was developed to analytically obtain sensitivity derivatives for the two-dimensional Euler equations using the material derivative concept of continuum mechanics. Several inverse design optimizations were performed to evaluate the merits of the analytical approach in comparison with the finit...
Effects of instantaneous power-supply failure on the operation of slip-energy recovery drives Cadirci, I; Akcam, G; Ermiş, Muammer (Institute of Electrical and Electronics Engineers (IEEE), 2005-03-01) In this work, performance analyses of slip energy recovery drives during and at recovery after instantaneous power-supply failure in one or more supply phases have been carried out. Transient slip energy recovery drive currents and voltages under such fault conditions have been obtained theoretically using mathematical models which take into account the three-phase, single-phase, and disconnected power-supply conditions. A detailed set of theoretical and experimental results is given to clarify the expected...
